Japan’s Sharp, maker of huge-screen televisions, voiced confidence Thursday as it told reporters Apple isn’t much of a concern. What about the almost incessant chatter that the tech giant will enter the TV manufacturing market with an iTV in 2012? “It’s not something we’re studying very hard,” an executive claims. Unclear whether this is bravado or whistling past the graveyard, but perhaps Sharp missed class the day Apple mangled a whole string of industries thought to be untouchable.
